Last year, more than 56,000 angina patients across the U.K. were denied life-saving CT heart scans due to the continuing shortage of radiologists and scanners, according to data released Nov. 8 by the Royal College of Radiologists (RCR) and the British Society of Cardiovascular Imaging (BSCI), published in The BMJ.

Researchers from the Netherlands demonstrated, in a study published Oct. 30 in Radiology, that four-dimensional (4D) flow MRI with automated cardiac valve tracking reduces analysis time and improves reliability of valvular flow quantification compared to manual valve tracking in patients with congenital heart disease.

A patent filed in 2014 by Apple Inc. for a new method to print three-dimensional (3D) models using triangular tessellation was recently approved by the U.S. Patent and Trademark Office on Tuesday, Oct. 23, according to a report by TechCrunch.com.

Using MRI technology, researchers from Washington University in St. Louis have found the cerebellum—a part of the brain long ignored by scientists—is more involved in higher-order thinking than previously thought, according to a report published Oct. 25 by NPR.

Kinetic imaging in x-ray angiography outperforms digital subtraction angiography at providing better image quality and reducing radiation exposure for improved viewing of small blood vessels, according to research published online Oct. 16 in Radiology.

Augmented reality (AR) allows cardiologists to visualize and explore three-dimensional (3D) myocardial scarring images in the heart as they perform ventricular tachycardia ablation or other electrophysiological surgical interventions, according to research published in PLOS One.

Cardiac MRI can accurately diagnose patients with pulmonary hypertension (PH), according to an Oct. 23 study published in Radiology. Results may help improve PH detection rates and enhance care for patients with severe cases.
